Hello, I have looked through the H90 manual and the algorithms and it seems to me that it can only do two effects at the same time. I am correct or perhaps I have missed something.
Hey,
I think you have missed that, while many H9/H90 algorithms each have one effect, many others have multiple effects simultaneously. Some examples:
SPACETIME = modulation + reverb + dual delay (where the signal path of the reverb and delay are reconfigurable (parallel/series) using the reverb level parameter)
MODECHOVERB = modulation (MOD) + single echo (ECHO) + reverb (VERB)
SPRING = spring reverb + tremolo
PITCHFUZZ = fuzz + dual delay + detune
EQCOMPRESSOR = EQ + compressor + trim (which adds some grit)
STICKY TAPE = drive + compressor + modulation/doubling/slap
AGGRAVATE = fuzz + octaver + tremolo + envelope follower
In H90 Control, the H90 algorithms have boxes that group effect parameters and that can sometimes help you see the different effects. Unfortunately, the H9 algorithms do not have those boxes so the different effects can be a little harder to see.
Hope that helps.
